摘要
为了能直观、全面了解对称三相电路的特点并加深理解中线在不对称三相电路中的作用,采用Multisim软件对三相电路仿真的方法,通过万用表的测量值以及示波器的实时波形,分析实验结果并验证理论;与实验室实际操作相比,该方法不仅无危险性,而且具有许多实验室实际操作无可比拟的优势,对提高教学效果具有十分重要的作用。
In order to understand the characteristics of three-phase circuit visually and roundly,and make students understand the effects of midline in asymmetry three-phase circuit,The Multisim was used to simulate three-phase circuit.The results of experiment are analyzed and the theory is validated through the value of multimeter and the waves of oscillograph.It is safe and has many advantages by contrast to actual management in the experiment lab.It is very important to improve the effect of teaching.
